'marea This invention relates to machines for performing -nishingl operations upon boot or shoeparts. As herein illustrated, the in-l ventionisenjibodied Yin an upper seam press- 5 ing machine of the general type described in United StatesLetters Patent No. 1,570,057, granted January 19, 1926, and No. 1,701,845, grantedlebruary12,1929, both in the name otF. M.V'Furber.

An object of :thepresent invention is to reorganize and simplify the construction of machines,- ofV the above type to obtain still greater ethciency of operation and to enable such a machine to operate With less vibra- 15 tion and to continue tc operate for more i extended periods Without disadvantageous Wear: and Without, being liable to get out of order. i 'With the above and other objects in view, as Will hereinafter appear, the present inventioni comprises various improvements in thel construction and relative arrangement ofpartsin: machines of the general type referred to. 'Asherein illustrated, these improvements include the provision, in a machine having seam pressing Vmeans and a rotaryV Work 'support,'foli parallell shafts conne'cted to be driven one from the other and respectively connected to operate the seam pressing means andto rotate the Worksup' port,'and an electric motor directly connectedv rEhe parallel arwith one of said shafts, rangement of the shafts enables them to be driven one from lthe other by meansof a sprocket chain and, as shown', a chain of the silent drive type is employed .for the purposeof reducing noisel and vibration to a minimum. 'Y The lparallel shafts are shown as arranged 4one above the other, the upper shaftcarrying an eccentric for operating the seampressing means and being directly connected With vthe motor, While the lower shaft is. connected with the rotary Work support` by means including a pair of relatively lslidable'intermeshing gears arranged to permit vertical adjustment of the work support Witheut interfering with the driving connec tions between theworlr support and the lower shaft. c It` is particularly advantageous to have the upper shaft directlyconnected with the motor,v as, described, inasmuch? as A, the uppery drives', the seam` pressing means; andconsequently encounters more resistance and req ,irestq be driven at greater, speed than the loyverfshaft'. f i i The mechanism 'of the `illustrated machine, with the 'exception ofthe parts which engage' the Work, is enclosed Within f andl protected by meansl Of a frame comprising af hollow` base, .upon which is mounted, the rotary Werk support, and a, hollow standardjrisingfrom the, base. having a portidn,o verhanging, the WorkA support and, carrying,V the seam pressing means. The yupper,andflovver shats` are disposed, respectively, `in ther overhang ing portionA oiftlielstandard; and in the base, While thechain connecting these shafts. isr conveniently locatedjvithin the upright por,- tie-n of the standard,v` The Work supportand:y

Themechanism of the illustrated machine,

with the exception of the instrumentalities which operate upon the work, is'enclosed Vwithin a casing comprising a substantially rectangular hollowfbase 10 upon which is mounted a rotary work support, and a hol-V lowV standard or gooseneck 12 rising from one end of the base and formed with an overhangingupper portion 14 which supports the seam pressing instrumentalities. An electric motor is confined within a housing 16 at one end of the upper portion 14 of the standard,

. the overhanging upperV portion 14 kof the standard `and is journaled inV bearings 26 therein. The housing 16 is suitably ventilated to enable the fan 22 to produce circulation `of air forthe purpose of cooling theA motor. 'One end of the armature shaft 20 is jcurnaled in a suitable bearing carried by the outer portion of the housing 16 while vthe in* ner end of said shaft is received within an axial socket 28 formed in the adjacent end of the main'driving shaft. One of the bearings 26 is arranged to 'support the shaft 24 at4 its sock'eted en'd, thus also providing a support for the innerend of the armature shaft which Aprojects into the socket 28telescjoping with the'shaft 24, so as to insure against unduevibration vofthe armature shaft ysuch as might occurif it should be supported entirely' by an overhung portion of the shaft 24. In addition to the bearing just referred to there are tworother bearings 26 whichare spaced Y 24 to provide vibrationless support for means,

lhereinafter.fdescribed, which actuates the seam pressing instrumentality, -The motor is positively7 connected with thed'rivii'ig'shaftl 24 byf'nieans of a `plurality of driving Vpins 304 carried by Yal disk-like head. 3 2 integral with Vthe driving shaft 24 and slidably re-V ceived in suitable apertures'formed in a disk 34'iixedto the armature shaft. This directly connected telescoping arrangement..V ofV the two shafts 2O and 24 insures accurate arialv Y alinement ofthe shafts and positive driving connections therebetween irrespective .of

slight inaccuracies in the -machinin'gof the adjacent parts of theniotor housing- V Inasmuch as one of the bearings 26 surroundsthe telescoping ends ofthe motor and driving shafts, accurate alinementof these shafts and smooth-running of thefhigh speed driving' shaft is insured. As a result of this construction, also, the adjacent ends of the driving and armature shaftsare supported by a single bearing only. The described manner of coupling the shafts and 24 enables the shafts to be uncoupled without the use of tools in order to permit the removal of the motor and without the necessity of disturbing the driving connections between the shaft 24 and the operating instrumentalities ofthe machine.

A horizontal shaft 36,'disposed in parallel relation to the driving shaft 24, is journaled in bearings 88 within the hollow base 10 and is driven from the shaft 24 byfineans of a silent Ychain 40 passing over sprocket wheels 42 and 44 of the saine diameter on the shafts 24 and 36, respectively, the arrangement lbeing such that the chain' 40 is located entirely within the n hollow base 10 and the upright portion of the standard 12. At the opposite extremity of theshaft 36 from the sprocket wheel 44 is located a worm 45, and this worm drives a worm wheel 46 which is fast fon the hub of a spur gear 48. The gear 48 is mounted to turn freely upon avertical rod 50 rigidly secured atits opposite ends in bosses formed within a detachable end portion 52 ofthe hollow base 10 and arranged to prevent axial displacement of said worin wheel and gear. The detachable portion 52 is secured to the basel() by means of screws 54 (Fig. 3) which, as shown, are countersunlr to prevent them from interfering with the work. By removing the -screws 54, theend portion52 may be removed, together with the worm wheel 44 andthe gear 48, to afford convenient access tothe adjacent parts of the mechanism. The gear 48 vis'made of unusual width," and meshing therewith is a relativelynarrow` gear y56'wh`ich is fast upon thelower end of'a verticalfshaft 58.

'The shaft 58isjournaled in a suitable bushing rigidly secured w'vithina cylindrical slide 60M andthe slide 60-is movable vertical-ly within a guiding sleeve 62 which projects upwardly from the base 10, and the slide carries a rotaryV work-supporting roll 64. The slide G0 is normally held` yieldingly inan upper position by meansof a spring-pressed lever 66 which is pivoted upona horizontal rod v6 8 carried bythe base 10a`nd which extends'bef Vtween the depending ears 70 of ltheslide 60,Y

With this arrangement the standard will not obstruct the path of j feed of the work, and' various .switches able fuse block, or cut-out 168, and main line switch 170 with electric terminal wires entering the casing at 172. A pilot light 174 may be connected with the'heat cont-rolling switch 168 in parallel with the wires'of the I heating circuit and contained, as shown inY Fig. 1, within a compartment 176 which is Iformed within the casino and o )ens toward the front of the machine, the pilot light being protected from breakage by a skeleton shield 17 8. The rheostat 162, as illustrated, is made in the form of a unit attached to the outer end of the overhanging portion 14 of the cas- "ing, rlhe contactsron the rheostat are enclosed within a perforated cover plate 180 and removably secured in place by means of lscrews ,182, and the contact lever or operati ing handle 184e projects through a slot 186 in the side of the coverplate, theends of the slot Alimiting the extent of movement of said lever. It will be noticed that while the lever or foperatinghandle'ofthe rheostat is located at the front of the machine conveniently Vnear rthepointv ofcperation ofthe seam pressing instrumentalities uponfthe work, Atheposition of said handle is such that 1t. is incapable of obstructing' the feed or interfering with the free manipulationofthe work. Inasmuch as the rheostaty 1s located somewhat above the plane of the worlnthe setting of the rheostat is'un'likely to be accident-'ally shifted during ,switch 1,88, located above the heat controlling the-operation of the machine. 'A suitable switch 166, isy connected in'any usual'or convenient manner with thel motor. Alli the 'i switches, as well as the connection block V164i i. and'the'fuse blcck 168,.,are entirely enclosed within and protected by thehollow standard V 112, and the operating handles ofthe switches project throughtherwall of `the'standardV 12 atthe front of the machine where they are. conveniently accessibleto the operator. By r theprovision of separate switchescontrolling the Vheat-and power, the operator is enabled to turn on the heat before starting the -machine so that the 'seam pressing instrumen- `talities maybe heated to the desiredtemperarangement of the driving shaft and the motor,I

and the construction of the transmission" mechanism,ithe machine is capable of operating at' high speed and substantiallyY withoutA vibration and noise. vThe character of the motion imparted to the operating parts is such that the machine may be depended upon tok operate over a long period without appre-` ciable wear and without need of repairs. All parts except those which engage the work being enclosed within the casing,'the work is thus protected from oil and the mechanism is protected from lint and dust.` Furthermore, the various devices for effecting adjustment of the operating parts, as well as the switches and other means for controlling the Vsupply of electric current,whilelreadily accessible to the operator, are solocated as not to interfere in any way with the feeding or manipulation-of the work.4
